- OR odds ratio, β ordinary least squares regression beta coefficient, CI confidence interval, Ref reference group. All Bonferroni-adjusted p-values < 0.001. Odds ratios indicate changes in odds of being frailer associated with being in the case group relative to the comparison group without mental disorders. Model 1—unadjusted; Model 2—adjusted for age, sex, ethnicity, highest qualification, Townsend deprivation index, cohabitation with spouse/partner, smoking status, alcohol intake frequency, systolic and diastolic blood pressure, body mass index, cholesterol, multimorbidity count and assessment centre
